About this replacement
Samsung NT930SBE-X716 Series — 15.4V Li-Polymer Replacement Battery (AA-PBTN4LR)
This is a 15.4V, 3500mAh (53.9Wh) lithium-polymer replacement battery for the Samsung 930 and 950 series notebooks. It fits the NT930SBE-X716, NT930SBV, NT950SBE-K38, NT930SBE-K38W, and over 53 additional Samsung 9-series laptop models. Part numbers AA-PBTN4LR and AA-PBTN4LR-05 are both covered by this cell.
- Samsung 930 and 950 series platform fit: These models share a common 15.4V battery rail, identical connector pinout, and the same BMS handshake protocol. One replacement cell covers the full variant range without adapter or firmware modification.
- Bench tested on actual hardware: We ran this cell on the NT930SBE platform and confirmed the BMS completed its initialisation handshake, the fuel gauge IC registered the cell, and charge cycling proceeded normally through all four charge stages without interruption or error flags.
- Post-install discharge cycle on Samsung 9-series: After fitting this battery, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in Samsung Settings after every cell swap.
BIOS reporting battery health as poor immediately after swap
The Samsung 9-series BIOS reads health data stored in the old cell's EEPROM and compares it against the new cell on first boot. Because the new cell has no usage history, the BIOS flags it as unknown or degraded — this is a data mismatch, not a fault with the battery. Running one full discharge-to-cutoff followed by an uninterrupted charge to 100% forces the BIOS to rewrite the learn-cycle data against the new cell. After two or three full cycles, Samsung Settings and the Windows battery report will align to the correct capacity and show a healthy status.
Laptop shutting down at 20–30% charge shown on screen
This symptom appears when the fuel gauge IC has not yet calibrated to the new cell's actual voltage curve. The reported percentage drifts from the real state of charge, and the system triggers a low-battery shutdown before the gauge catches up. It is most noticeable under full CPU and display load, where current draw accelerates the voltage drop faster than the uncalibrated gauge expects. Run two complete discharge-to-hibernate and full-charge cycles to let the fuel gauge IC re-map the voltage curve — the shutdowns stop once the gauge tracks correctly, typically by the third cycle.
